Inkqubo yothumelo "yibhulorho" phakathi kombane webulldozer ukusuka enjini ukuya kwindlela yokuhamba, kwaye iibheringi kufuneka zimelane neziphumo ezidityanisiweyo zetorque ephezulu, impembelelo, kunye{0}}nesantya esiphezulu sokujikeleza:
Ukuhanjiswa: Inkxaso ye-shaft ye-gear yangaphakathi ixhomekeke kwi-tapered roller bearings (ekwaziyo ukumelana nemithwalo ye-radial kunye ne-axial) kunye ne-cylindrical roller bearings (elungelelaniswe kwi-radial forces ngesantya esiphezulu) ukuqinisekisa ukuhanjiswa kwamandla okuzinzile ngexesha lokutshintshwa kwegiya kunye nokunciphisa iimpazamo ze-gear meshing.
Ishaft yokuqhuba: I-shaft ye-drive edibanisa i-gearbox kunye ne-axle yokuqhuba, kwaye iibheringi zayo ezixhasayo ubukhulu becala -zilungelelanisa iibheringi ezizilungelelanisayo, ezikwaziyo ukuziqhelanisa nokuphambuka okuncinci kwe-shaft yokuqhuba okubangelwa ziimpazamo zofakelo okanye amaqhuma, ukunqanda ukuzala.

I-axle yokuqhuba: Iibheringi kwezona ndlela zinciphisayo kunye nokwahlulahlula kufuneka zimelane netorque enkulu yokugqibela yothumelo, kwaye iibheringi ezinerola ezinemiqolo ephindwe kabini ziqhele ukusetyenziselwa ukusasaza imithwalo ngokwandisa amandla onxibelelwano. Inkqubo yokuhamba idibana ngokuthe ngqo nomhlaba, kwaye iibheringi kufuneka zimelane nobunzima be-bulldozer ngokwayo (amashumi eetoni) kunye namandla okusabela komhlaba ngexesha lokuqhuba kunye nokusebenza:
Ivili lokuqhuba: Elona candelo liqhuba ukusebenza kwengoma, kwaye iibheringi zayo ubukhulu becala -zinkulu umqolo ophindwe kabini iibheringi ezine tapered. Umsesane wangaphandle ulungelelaniswa ne-hub yevili, kwaye iringi yangaphakathi igxininiswe kwi-shaft yesiqingatha, enokumelana nemithwalo enzima ye-radial kunye ne-axial thrust, ukuqinisekisa ukuba umzila awutyibiliki okanye uphambuke.
Ukuxhasa kunye namavili axhasayo: Ukuqengqeleka ecaleni kwendlela ukuxhasa umzimba, iibheringi kufuneka zibe nokuxhathisa okuqinileyo kunye nokutywinwa. Iibheringi ze-roller ezitywiniweyo (ezifana neebheringi ze-cylindrical roller kunye nezangqa zokutywinwa zerabha) zihlala zisetyenziselwa ukukhusela umhlaba kunye nesanti ukuba zingangeni - ngakumbi kwiindawo ezinodaka, imigodi kunye nezinye iindawo, ukungaphumeleli kwetywina kunokubangela ukunxiba ngokukhawuleza.

Ivili elikhokelayo: likhokela indlela eya ngakulo, kwaye iibheringi zayo zihlala zizilungelelanisa-iibheringi ezizilungelelanisayo, ezinokuziqhelanisa nokutenxa kwe-engile okubangelwa lutshintsho kuxinzelelo lomkhondo kunye nokunciphisa isenzeko somzila "wokugaya".
Iibulldozers, izixhobo zokukhulula, kunye nezinye izixhobo zokusebenza ziya kuvelisa iimpembelelo ezinzima kunye namandla asecaleni ngexesha lokusebenza, kwaye iibheringi kufuneka zibe nokuguquguquka kwe-swing kunye nokuchasana kwempembelelo:
I-Bulldozer blade hinge shaft: Kwi-hinge shaft edibanisa i-bulldozer blade kunye ne-cylinder yeoli yokuphakamisa, iibheringi ezidibeneyo (ii-radial joint bearings okanye ii-angular joint joint bearings) zisetyenziselwa ukuvumela i-blade ukuba ijikeleze kwi-angle ethile ngexesha lokunyusa kunye nokuthambeka, ukuphepha ukugxininiswa koxinzelelo olubangelwa ukudibanisa okuqinileyo. Ezinye iimeko zisebenzisa iself-i-lubricating joint bearings (kuquka izithambisi eziqinileyo) ukunciphisa iindleko zogcino olubangelwa kukuthambisa rhoqo.

Isixhobo sokukhulula: I-shaft edibanisayo phakathi kwamazinyo akhululayo kunye nefreyimu kufuneka imelane nempembelelo xa ifakwe kumhlaba oqinileyo okanye ilitye. Ubukhulu becala sisityatyambo esikhulu esingqukuva okanye ibheringi etywiniweyo, ethi ilungelelanise ukunxitywa kokumelana kunye nomthamo webuffering.
Ukusetyenziswa kweebheringi zebulldozer kufuneka kuhlangabezene neemfuno ezingundoqo ezintathu:
Ukuthwala umthwalo onzima: Uyilwe ngesakhiwo (i-roller bearing line contact) kunye nempahla ({0}}yamandla aphezulu entsimbi) ukulungelelanisa imithwalo yamashumi eetoni;
Ukunyamezela indalo esingqongileyo: Isakhiwo esitywiniweyo (i-labyrinth, i-double lip seal) kunye nokunxiba-izinto ezikwaziyo ukumelana nokukhukuliseka kothuli, udaka, amanzi kunye nobushushu obuphezulu;
Ukuguquguquka kweDynamic: Iibheringi ezikhethekileyo ezifana ne-centering kunye ne-joints zivumela ukuphambuka okuncinci okanye i-oscillation yamacandelo, ukuphepha ukungaphumeleli kwangaphambili okubangelwa uxinzelelo oluqinileyo.
